Generation Rate Constraint

Generation Rate Constraint(GRCs): The Load frequency Control with Generation Rate Constraint problem discussed so far does not consider the effect of the restrictions on the rate of change of power generation. In power systems having steam plants, power generation can change only at a specified maximum rate. The generation rate (from safety considerations of the […]

Automatic Voltage Control

Automatic Voltage Control: Automatic Voltage Control – Figure 8.20 gives the schematic diagram of an automatic voltage regulator of a generator. It basically consists of a main exciter which excites the alternator field to control the output voltage. The exciter field is automatically controlled through error e=Vref-VT suitably amplified through voltage and power amplifiers. It […]

Two Area Load Frequency Control

Two Area Load Frequency Control: Two Area Load Frequency Control – An extended power system can be divided into a number of Two Area Load Frequency Control areas interconnected by means of tie lines. Without loss of generality we shall consider a two-area case connected by a single tie line as illustrated in Fig. 8.13. […]

Load frequency Control and Economic Dispatch Control

Load frequency Control and Economic Dispatch Control: Load frequency Control and Economic Dispatch Control – Load frequency control with integral controller achieves zero steady state frequency error and a fast dynamic response, but it exercises no control over the relative loadings of various generating stations (i.e. economic dispatch) of the control area. For example, if […]
